If the above method is for editing auto test step (as mentioned below), constant
voltage range can also be set.
3.2.3 Constant resistance operation mode (CR)
Under CR mode, the electronic load is equivalent to a constant resistance (as
shown below) and will give linear change of current with input voltage change.
As shown in Fig. 3-3.
Fig. 3-3 Voltage-Current Relation Schema under CR Mode
Under CR mode, the electronic load provides three ways to modify constant
resistance.
Rotate adjusting knob to set constant resistance value.
Use numeric keys to input resistance value and press [Enter] key to
confirm set constant resistance value.
Use
moving cursor and press to adjust values at
corresponding positions.
Operation steps
1. Press [CR] key and [Shift] +[CV] to enter parameter setting screen.
Constant Resistance
Range=7500.0Ω
2. Set maximum working resistance value and press [Enter] for confirmation.
Constant Resistance
Range=2000.0Ω
3. Set maximum voltage value and press [Enter] key.
Constant Resistance
High=130.0V
4. Set minimum voltage value and press [Enter] key.
Constant Resistance
Low=0.000V
5. Complete parameter setting.
10.0000V 0.0000A
0.00W CC=2.000Ω
NOTE
If the above method is for editing auto test step (as mentioned below), constant
resistance range can also be set.
